Choose the answer that best describes the geologic process that contributes to the formation of fault-block mountains.

The Earth's crust stretched from swelling underneath and vertical movement by blocks generates steep scarps.

The Earth's crust is pulled apart creating deep folds and then pushed together generating steep scarps.

The Earth's crust is pushed together which tilts layers of rock on their side producing steep scarps.

The Earth's crust is pushed together which forces up blocks vertically creating steep scarps.

The answer that best describes the geologic process that contributes to the formation of fault-block mountains is:

The Earth's crust is pulled apart creating deep folds and then pushed together generating steep scarps.

Fault-block mountains form as a result of tectonic forces that stretch and pull the Earth's crust, leading to the formation of faults. Blocks of the crust then move vertically along these faults, resulting in steep scarps.
